行为和事件相关电位（ERP）被记录，而参与者作出真实和欺骗性的反应，以前记住的话在三个教学条件：一致的真实，一致的欺骗，随机欺骗。为了确定练习是否会影响我们之前报道的欺骗相关活动[R。小约翰逊，J. Barnhardt，J. Zhu，欺骗性反应：反应冲突和策略监控对晚期积极成分和情景记忆相关脑活动的影响。生物心理学，64（2003）217-253-1 R约翰逊，Jr.，J. Barnhardt，J. Zhu，执行过程对欺骗性反应的贡献。Neuropsychologia，42（2004）878-901]，参与者对每种情况进行了两组145次试验。在一致的真实条件下，实践中受益的表现，减少反应时（RT）和RT的变异性。此外，练习增加了P300的振幅，降低了内侧额叶负波（MFN）的振幅，这被认为是使用反应监测过程的指标。然而，在两种欺骗条件下得到的结果不同。虽然练习减少了RT几乎一样多的一致的真实条件下，在这两种条件下的欺骗反应的程度比那些在一致的真实条件下实际上略有增加。因此，反应时反映冲突反应信息处理的成分没有减少。在与RT结果一致的雅阁中，在一致的欺骗性和随机欺骗性条件下，最惠国待遇的幅度不受实践的影响，这表明，执行过程所需的数量和/或监测欺骗性反应是不减少的实践。在一致性欺骗条件下，P300波幅略有增加，而在随机性欺骗条件下，P300波幅无明显变化。因此，这里的一个主要发现是，不像真实的反应，概念驱动的反应冲突潜在的欺骗性反应似乎是抵抗实践引起的变化，如前所述的感知驱动的反应冲突。(c)2005 Elsevier B.

Behavior and event-related potentials (ERP) were recorded while participants made truthful and deceptive responses about previously memorized words under three instructional conditions: consistent truthful, consistent deceptive, and random deceptive. To determine if practice affected the deception-related activity we reported previously [R. Johnson, Jr., J. Barnhardt, J. Zhu, The deceptive response: effects of response conflict and strategic monitoring on the late positive component and episodic memory-related brain activity. Biol. Psychol., 64 (2003) 217-253-1 R Johnson, Jr., J. Barnhardt, J. Zhu, The contribution of executive processes to deceptive responding. Neuropsychologia, 42 (2004) 878-901], participants performed two blocks of 145 trials of each condition. In the consistent truthful condition, practice benefited performance as indicated by decreased reaction time (RT) and RT variability. In addition, practice increased P300 amplitude and decreased the amplitude of a medial frontal negativity (MFN), which is believed to index the use of response-monitoring processes. However, a different pattern of results obtained in the two deception conditions. Although practice decreased RTs by almost as much as in the consistent truthful condition, the extent to which deceptive response in both conditions were slower than those in the consistent truthful condition actually increased slightly. Hence, the component of RT reflecting processing of conflicting response information did not decrease. In accord with the RT results, MFN amplitudes in the consistent deceptive and random deceptive conditions were unaffected by practice, suggesting that the amount of executive processes required to make and/or monitor deceptive responses was undiminished by practice. Although P300 amplitude increased slightly in the consistent deceptive condition, there was no change in the random deceptive condition. Thus, a major finding here is that, unlike truthful responses, the conceptually driven response conflicts underlying deceptive responses appear to be as resistant to practice-induced changes as described previously for perceptually driven response conflicts.
